SPECIFICATION forming part of Letters Patent No. 794,258, dated July 11,1905.

Application filed August 8, 19011. Serial No. 219,878.

To a/ZZ whom, it may concern:

Be it known that I, NICHOLAS A. SMITH, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements in Bungs;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in bungs for dispensing liquidsfrom a containing vessel in which the bung is inserted; and its objectis to provide a dispensing tube or faucet and a bung with means foradmitting air, gas, or other fluid to the containing vessel, to providemeans for automatically and simultaneously opening and closing the fluidand air passages when the dispensing tube or faucet is attached to ordetached from the bung, and to provide the device with certain new anduseful features hereinafter more fully described, and particularlypointed out in the claims.

My invention consists, essentially, of the combination, with a bung anda dispensing faucet or tube adapted to be attached to the bung, of airor gas induction means consisting of an air-tube in the dispensing tubeor faucet, a tubular bolt adapted to both operate the valves and conveythe air, an air-valve to close the air-passage, and means forautomatically connecting the air-tube with the bolt, whereby an air orgas passage is provided in conjunction with the bung and dispensingtubeand the valve to close the air-passage is automatically andsimultaneously operated in conjunction with the valve to close thepassage for the fluid, and in the combination and arrangement of parts,as hereinafter more fully described, reference being had to theaccompanying drawings, in which- Figure l is a longitudinal sectiontaken through the axis of a device embodying my invention, showing thesame in open position; Fig. 2, the same, showing the bung in closedposition and with the dispensing attachment removed; Fig. 3, anelevation showing the outer end of the bung; Fig. A, the same,show ingthe inner end of the bung with the airvalve in open position; Fig. 5, adetail of the dispensing attachment; Fig. 6, a detail showing theHuid-dispensing valve in open position, and Fig. 7 a detail of the boltfor operating the valves.

Like letters refer to like parts in all of the figures.

A represents the bung proper and having a hollow body and also adaptedto be inserted in a suitable keg, Cask, or other fluid-retaining vessel.This bung is provided with a valveseat on its inner end and withopenings B to permit the escape of liquids when the valve is in openposition. These openings are closed by a valve K, mounted on a bolt I,extending through the aXis of the inner end of the bung and providedwith an angular head within the bung, by which the bolt and valve areturned.

E is a dispensing tube or faucet by which the liquid is conveyed away toany convenient place. This tube may terminate in a faucet instead of ahose-nipple E', as shown, if preferred. To attach this tube and form atight closure between this and the bung, the latter is provided with anannular seat C, surrounding the tube, and a packing-ring D is providedon the tube E to engage this seat and form a tight joint. The tube isattached and held in place by means of spiral grooves Q and lateralopenings It in the interior of the bung and lugs IJ on the tube, whichlugs enter the openings It and engage the grooves when the tube isrotated to place. The inner end of the tube Eis closed and provided witha socket G to receive the head of the bolt I and turn the bolt as thetube is turned to place, and thus open the valve K.

H represents lateral openings to permit the liquid to pass from theinterior of the bung into the tube E. The valve K is provided with asuitable gland or packing L and adjusting-nuts M, whereby no iluid canpass alongside the bolt, and the valve is also yieldingly forced againstits seat and the openings B tightly closed when the valve is turned overthe sanne. As so far described the device is not new.

My invention consists in the following additions and modifications, towit: In the axis of the tube E, I provide an air-tube F, having itsouter end adapted to attach a hose, through which air or gas underpressure or otherwise is admitted. The inner end of this air-tubeprojects within thel socket Gr, and the bolt I is made tubularthroughout all but the extreme inner end, as at 1/, and provided withlateral openings J near its inner end. The air-tube F connects with thistubular bolt by being inserted in the head ot' the same, and a packingD', surrounding the air-tube, engages the end of the bolt and forms atight joint between the bolt and the air-tube. A yokeN is attached tothe inner end ot' the bung A in any convenient manner and is providedwith a valve-seat O opposite the end of the bung, and the boltI isprolonged inward, and journaled in the axis oi' this yoke and mounted onthis bolt is an air-valve K', provided with a gland or packing L andadjusting-nuts M', acting in the opposite direction to the correspondingvalve, packing', and nuts, that operate to close the openings B.

In the Valve K/ are radial grooves J, located opposite the openings J,into which grooves the air escapes, and when the valve is open thesegrooves extend beyond the edge vof the valve-seat O, as in Fig. 4, andwhen closed the said grooves are opposite the said seats, so that no aircan escape therethrough. rlhe bolt is iiattened at oppositesidesopposite the valves, as atl@ and the valves provided with openingsto iit the same, (not lshwn whereby the valves are turnedby the 'o t.

When the tube E is inserted and turned to place, the socket Gr engagesthc bolt-head and turns the bolt and valves and opens both valves at thesame time. The packings D and D are compressed and form tight jointsbetween the bung and tubes and the air-tube and bolt. The air or gaswill then iiow in through the air tube and bolt and escape through thegrooves J/,and the liquid will flow out through the openings B into theinterior of the bung and thence through the openings H, tube E, andnipple E. Then the tube Eis detached, it must be turned back until thelugs Q are opposite the openings R, and this turns the bolt and valvesto closed position and effectually closes both the air and liquidpassages.

l claim- 1. The combination of a bung, a dispensingvalve rotative on theinner end of the bung, a yoke attached to the bung, an air-valveengaging the yoke, a tubular bolt to operate both of said valves, adispensing-tube adapted to be attached to the bung, and having' a socketto turn the bolt, and an air-tube in the xs of the dispensing-tube andengaging the 2. The combination of a bung having end openings and anannular seat, a valve rotative on the end of 'the bung and closing thesaid openings, a yoke attached to the bung and having a valve-seatopposite the end of the bung, an air-valve engaging the seat on theyoke, a tubular bolt tooperate the valves, a dispensing-tube having apacking to engage the seat in the bung, and also havingasocket to engagethe bolt, and an air-tube in the axis of the dispensing-tube andconnected with the bolt.

3.
